To all whom it may concem:

Be it 'known that I', JOHN B. OWENS, e citizen `0f` the United States, resid'ng at Mnchen, County of Middlesex, and" State of New Jersey, have invented certain` new and useful "Imprbvements Sanitary In cinerato'rs,` of whiehthefollowing isa spec `fieajci o'n.a` w "qw a i i\ Mi This invention relates to sanitary incinerators, 'and' i more particularly? to incinera tbr 'jfrf *use 'in eonhje'tion With vvaste' fheat tutions', or* "other plee'sjwhe rew large" mlm;-

The chambers 1 and 2 may be 'of any desired length and located in any preferred position and need not be disposed close to the source of wasteheat as any suitable connections thereto, 'and to the draft `'stat-k, may be employed. In Fig. 1 'a steam boiler furnace is shown at 6 which has the waste heat space or fiue 7 communicating by an opening 8 with the cham 'bers 1 and 2. The stack appears at 9. The entire Volume of waste heat may pass to the stack 9 through the incinerator, or, 'only a portion of such waste heat may be by-pa'ssed for utilization by the invention. Any suitable damper or valve 10 is used to control admission of the waste heat to the chamber 1. -A sliding damper which can be held in raised position by a chain or other connection 11, is shown. At the exit end of thechamber l there is a damper 12 which may be of any preferred form. The damper shown is Suspended by a chain 13 and may be arranged so that there is a normal draft or bleed at 14 below the lower edge thereof tocarry ofi' any odors.

The nlet and outlet ends of the chamber 2 are controlled by any suitable valves or dampers, sliding 'dampers 15 and 16 being shown.

v Normally. the damper 10 is closed and the amper 12 slightly opento provide the bleed dampers 15 and 16 areopen to allow the waste heat to pass from the flue 7 and opening &through the ch'amber 2 into the stack 9. `During the passage of the waste heat the arch 'or partition 3 is heated and themater ial in the'chamber 1 is dried by the heat radiated through arch 3 into chamber 1. Under normal drying conditions the dampers are 'as shown in Figs. 1, 2 and 3. Theleak or bleed at 14 causes a down 'draft throughi the seat openings 4, to Carry ofl" odors 'l`he m aterial in chamber 1 having been suitably dred, the dampers 1:5 and 16 are closed and dampers 10 and 12 opened there'by admitting waste heat directly into the chamber 1. If the drying of the material in, chamber 1 has not been thoroughly efl ected 'by the radiation of heat from the chamber 2, the admission of waste heat into rapidly complete *the drying of the materia If'the temperature 5 for normally p of the gas circulating through the chamber 1 is not high enough to ignite the dried ma'- terial, ignition may be started by droppng u a iece of burning oil' waste, or' of any in ammable material* through one of the seat openings 4 into the chamber 1. fIf cornbustion is to :be accelerated, a small amount of *oi-l 'or other inflam- `mable material may be introduced into the charnber '1, but this would not ordinarily be necessary. i v I The -incineration of the dried material -in previously ignited, i

need only occur at tnes the danpers chanber 1, as described, intervals. At all other are in the position shown in Figs. 1, 2 and 3.

In Figs. 4 and 5 I have shown the incinerator and method of its operation applied to a tunnel kiln 17 which is provided with a stack or ehinney 18 and with outlets 19 connected to ;the stack by fiue 20. The incinerator which in Figs. 4 and 5 is shown generally at 21 may connect with the tunnel of the kiln -by a by-pass or outlet 22 leading to the upper and lower chambers 1 and 2 of said incinerator for the entry of the waste heat o'r the by-passing of a portion of the heat from the tunnel into the chambers l and 2 in the same manner as that shown in Fig. l. Dampers 23 and 24 control the admission of heat to the chambers 1 and 2. Dampers corresponding to the dampers 12 'and 16 control the outlet ends of the chambers 1 and 2. One of said damp'ers'is shown at 25 in Fig. 4. The Construction and'operation of the incinerator shown in Figs. 4 and 5 is in all respects similar to that of the inciner'ator previously described, the only difference being that the waste heat is derived from a kiln instead of a stean boiler.

Having thus described my invention what I claim as new and desire by Letters Patent is z 1. In a sanitary incinerator for the utilizatioh of products' of conbustion derived from a source extraneous thereto, an incinerating chamber adapted toreceive the material which is to be incinerated, a separate chamber for directly receiving the products of combustion, a wall between said 'chambers through which heat derived from the products of conbustion may pass from the heating cham'ber to the incinerating 'chanber, each of 'said chanbers having an inlet and an outlet, said inlets being arranged to receive, when open, the extrane- 3 to secure 'ous products of combustion, means for nordraft leakage through said outlet for the ventilation of said incinerating ch'anber.

2. A sanitary incinerator for the utilization 'of products of conbustion derived from a source extraneous thereto, having an incinerating chamber adapted to receive the inaterial which is to be incinerated, said chamber having an outlet, a damper for said outlet, suspending means 'for said damper which normally retains the danper in partially closed condition and prevents the eomucts of eonbuston, dampers for said nlet plete closng thereof, thus permtting a norand outlet, and a Wall between said chammal bleed or draft leakage from said nbers through which heat derved from the cineratng chamber for the ventlation thereproducts of combust'on may pass from the 5 of, said suspending means enabling the heating chambe' to the ncnerating chamdamper te be raised to wholly open the outber.
